Eric J. Loch Diamonds & Fine Jewelry

General information

We started in 1972 as Lochs, helping clients worldwide obtain uncut and cut gemstones. In 1984 we opened our jewelry store and have continued the tradition of helping our clients with the special events in their lives. We expanded and moved to our present location on the edge of Allentown in 2003. We specialize in engagement rings and other Diamond jewelry featuring Diamonds hand selected in Antwerp, Belgium by our Certified Diamond Grader. Each Diamond over 1/2 carat is graded to standards exceeding those used by outside labs such as AGS, GIA, and HRD. More importantly, our Diamonds are graded for Light Performance which is the only accurate measure of how the Diamond cutter transformed the raw Diamond rock into a scintillating ball of fire. Light Performance affects a Diamonds value by as much as 40%. Even our Certified Diamond Grader can not judge a Diamond solely based on paper. HE/She must see the Diamond in order to do a complete analysis.
We value knowledge and integrity which assures you that your Diamond has been accurately graded and evaluated by the Lehigh Valley region's only Certified Diamond Grader, and Master IJO Jeweler, working in the only Certified Gem Lab in the region.
We look forward to serving you!
